vMy invention relatesto a new and useful l improvement in a tire rim lock adaptedfor simplein structure, economical'ofmanu'fac locking the tire rim against removal from the wheel with which used.

It is an object of the present invention to..

provide a lock of this type which will be ture, composed ofaminimum number of parts, and easily and quickly assembled.

It is another object of the invention to providea lock of this class in which a retractablev f finger is used for locking purposes which is withdrawn from locking positionin a series of steps.

Other objects will appear hereinafter. u i

The invention consists in the combination;l

andy arrangement of parts scribed and claimed. i 1- .v

The invention will be best understood by a reference to the accompanying drawings which form a part of this specification and in which, y

Fig. 1 is a side elevational view of a wheel showing my invention applied.

Fig. 2 is a central longitudinal sectional view of the invention showingit applied.

Fig. 3 is a view taken on line 3- -3 of Fig. 2. Fig. 4 is a sectional view taken on line 4--4 of Fig. 3. f

' Fig. 5 is a sectional view taken on line 5 5 of Fig. 2. Y

In the drawings I have illustrated the invention used with a wheel 7 having a felly 8,

hereinafter df the sides of which are outwardly turned to provide the rim engaging flanges 9 and 10 against the outer ends of which engage the rim 11 upon which is positioned the tire 12. Mounted on the inner surface of this rim 11 is a plug 13 preferably formed from metal and provided with a centrally disposed recess 14 in which is adapted to slidably engage a slidably positioned arcuate locking finger 15.

Mounted upon the outer surface of the felly v 8 between the flanges 9 and 10 is a housing 16 which is provided in its end walls with the openings 17 and18 through which the locking finger 15 is projected as shown in Fig. 2. This locking finger is provided on its undersurface with a pluralityof teeth 19 and a plurality of notches 20. f

Formed in the side wall 21 of the housing is a key hole 22 extending into which is a pin 23 projecting from the side wall 24. Mounted in the sidewalls 21 and 24 is a pin 25 onwhich are formed the spaced teeth 26. A bow shaped leaf spring 27 is positioned in the housing and engaging at its opposite ends i the inner vsurface of the top ofthe housing adjacent the endsfthereoifthis top being cut' away as, at 28.

mounted in position. aipin 29` is projectedY through oneend of the finger 15, this pin preventing withdrawal `of the locking finger from the housing. The opposite lend of the preventsthe passage oft-he lockingifinger 15 through `the housing. v"

In operation,` after the-device has been mounted 'onthe' felly 8 inthe manner shown finger 15is provided with a heel 30` which.

in Fig. 2, lthe locking finger 15 mayl beretracted to disengagefromthe recess 14. vThis rim may thenl bev moved axiallyv from' the felly 8, the flange 10 beingcutaway as at 31.v p In :order vto* retract the .locking fingerl 15, fa

suitable key having ahollow stem is inserted l through the key hele 22, the pin 23,engaging in the stem of the key and serving as a guide. f y v The tonguesv 26 will be differently spaced depending upon the nature of notches cut in the key. The key is then rotated to engage in the notches 20, each rotation of the key effecting a retraction of the locking finger 15 the space of one of the'notchesy 2O so that in the type shown in Fig. 2 three rotations of the e key would be necessary for retraction of the locking finger to inoperative position. At i i the opening-28.

It is obvious from the description that the device is comprised of but few parts and may be easily and quickly assembled while at the same time its simplicity of structure permits an economical and durable arrangement.

While I have illustrated and described thel lpreferred form of my invention, I do notl wish to limit myself to the precise details of structureshown, but vdesire to avail myself for the of snchvariations and modifications as come.

within the scope of the appendedclaims.

Having thus described my invention what I claim as new and desire to secure by Let ters Patent is:

1. A device-of the class described adapted 60" lIn operatiom'after thel locking finger -15k is f f Vfelly.

for use YWitha vehicle Wheel havingl a fellyV and aiv rim lmountable thereon, comprising: a

Vhousing on said telly; a locking member-proi 2. A device of thenclassfde'scribed adapted for use' .With a felly having a rim mountedv thereon; comprising :a housing having openings formed in its end Walls; a locking bar projectedthrough 'said openings and adapted Y for extending outwardly-.from said housing; teeth on the undersurface 'of said locking memberengageable with the edge of the open ing in said housing for resisting movement of saidlocking member longitudinally; arecess bearing memberv mounted on and pro- 'ecting radiall inWardl i from said rim said loc-king member engaging said recess upon pro3ection outwardly of' said housing; and a spring in saidfhousingl normally Aretaining Vsaid locking member in engagement with the edge of said opening. f 31A device of the class described adapted for use with a vehicle Wheel having a 4telly and a rim mountable thereon, comprising: a f

housing mounted on Vsaid felly; anfareuate locking member proJected through openings formed in opposite Walls of said housing;

yteeth on the underside of said locking v"membei" adjacentone end 'engageable `With lthe 1 edge of the-opening in'said housing, and While inw engagement, preventing longitudinal movement of saidfloclring member; 'a yboivshaped leaf spring yin said housing normally retaining said locking member in engagement Withthe edge ofsaid housing; arecess Vbearing member mounted on and projecting radially rinwardly from said rim,` said lock@ ing member engaging inv said recess uponA projection outwardly vfrom said housing; oneY side of said housing having a key openingl formed therein;and a pin projecting from the inner vace'of the opposite Wall ofsaid housing in alignment WithA said key opening.

In testimony 'whereof I have signed the foregoing specification. y
